funny I can’t get a straight answer from anyone about the difference. I wrote twice on the “jb4 is out” thread asking what’s the diff ..... no answer.

So I ask again what the h$ll difference is there ?
why would anyone buy a jb4 instead of a jb1 ?

They have an upgrade option for people with a JB1. It shows what it adds.

You aren't getting an answer because there are several threads that have already answered that question and it's on their website's homepage.

Oh I see what you are asking. No I did not drive the car with JB4 yet. This is coming from agchenry, he installed it yesterday and was screaming like a 5year old on the phone out of excitement when I called him.

Was just at the shop today getting my AWE touring exhaust installed. While there I asked them about the JB1 and 4. They told me they won't go near them because they have seen too many bricked ECUs from the use of them. They also told me that Mercedes will definitely know that the car was tuned at anytime. No way to hide it. They told me this even though they do tune ECUs.

Not gonna lie, all that information does scare me a bit.

Ha! If you click on his name, you can go through his old posts. He doesn't contribute anything useful to the threads, but entertaining nonetheless.

Your shop must want your money. I’ve never heard of JB piggybacks bricking ECUs.
If they have happened. It’s few and far between

So are you suggesting that they only recommend the tune that they sell, but not the JB that they don't sell?

No, not at all, but I first thought that as well. I started researching bricked ECUs and found plenty out there. It has given me second thoughts on messing with my ECU at all.

Until there's more development on the JB4, it's a glorified JB1 with more monitoring. AFR needs to get figured out and stage2-3 management. I know it'll happen, but it's not there yet.

Disclosure: I've ordered a JB4 to check it out.

Information like this you have to take with a grain of salt. There is A LOT of room for user error with a piggy back, especially JB. You install it yourself and you can tune yourself (at your own risk).

Can you share where you were researching? I have read nothing about bricked ECU's involving BMS and Mercedes. I've read some issues on BMW forums but even the majority of those were due to user error.
